Protein Structure
|
|
Function |
Non-lysosomal glucosylceramidase that catalyzes the conversion of glucosylceramide (GlcCer) to free glucose and ceramide. Involved in sphingomyelin generation and prevention of glycolipid accumulation. May also catalyze the hydrolysis of bile acid 3-O-glucosides, however, the relevance of such activity is unclear in vivo. Plays a role in central nevous system development. Required for proper formation of motor neuron axons. {ECO:0000269PubMed:17105727, ECO:0000269PubMed:23332916}.

Subcellular Localization |
Endoplasmic reticulum membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Golgi apparatus membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Not localized to lipid rafts. {ECO:0000269PubMed:17105727}.
|
Disease Associations |
Spastic paraplegia 46, autosomal recessive (SPG46) [MIM:614409]: A neurodegenerative disorder characterized by onset in childhood of slowly progressive spastic paraplegia and cerebellar signs. Some patients have cognitive impairment, cataracts, and cerebral, cerebellar, and corpus callosum atrophy on brain imaging. {ECO:0000269PubMed:23332916, ECO:0000269PubMed:23332917}. Note=The disease is caused by mutations affecting the gene represented in this entry.
|
Tissue Specificity |
Widely expressed. Highly expressed in brain, heart, skeletal muscle, kidney and placenta and expressed at lower level in liver. {ECO:0000269PubMed:11489889}.
